The registration card may help with warranty going through the TV company. But, that's the last option.
You can fix it yourself by replacing this board. The board number should be BA71G0F01043.

The 8 Inverter transformer are the problem. They are on many TV power boards that are causing the same problems.
Ebay is selling a couple for $49. Good price I think.

If you decied to throw the board in the trash, let me know. I maybe able to help you fix it so you can have a spare board. I fixed mine that way.

Hi
A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this helps
